Making the most of low-grade silicon for cheaper, more efficient solar panels

While we wait for affordable multi-junction solar cells that are pushing past the 40 percent conversion efficiency mark to make it out of the lab and onto our roofs, we have to make do with standard commercial silicon cells that currently max out at around 19 percent. A team from the University of New South Wales in Australia has found a way to improve the quality of low-grade silicon, enabling higher efficiency solar cells to be produced from cheaper, low-grade silicon.

Spectrolab claims record efficiency for new solar cell

Spectrolab, a Boeing subsidiary known for the manufacture of solar cells for satellites and spacecraft, has in recent years turned its attention to terrestrial solar cells to tap into the expanding alternative energy market. Now the California-based company has claimed a new solar cell efficiency record of 37.8 percent for a ground-based multi-junction cell without solar concentration. Read More

Solar-powered Volta Racer is flexible about finding sunlight

If you want to teach children about hydrogen power, you can always buy them a fuel cell-powered toy car like the H-ROVER. Should you wish to show them the merits of solar power, there are also quite a number of solar panel-equipped cars from which to choose. ToyLabs’ new Volta Racer, however, is reportedly the first toy car to feature a flexible polycrystalline silicon solar panel. Read More

Multi-use Titanium Dioxide claimed to be the next "wonder material"

Graphene could soon be facing some competition for the unofficial title of “World’s Most Useful New Substance.” Led by Associate Professor Darren Sun, a team of scientists at Singapore’s Nanyang Technological University have spent the past five years developing a material known as Multi-use Titanium Dioxide. Their research indicates that it can be used to produce hydrogen and clean water from wastewater, double the lifespan of batteries, create antibacterial wound dressings ... and more. Read More

Triple-junction solar cell design could break 50 percent conversion barrier

The current world record for triple-junction solar cell efficiency is 44 percent, but a collaboration between the U.S. Naval Research Laboratory (NRL), the Imperial College of London, and MicroLink Devices Inc. has led to a multi-junction photovoltaic cell design that could break the 50 percent conversion efficiency barrier under concentrated solar illumination.

Stanford University researchers create peel-and-stick solar cells

Traditionally, thin-film solar cells are made with rigid glass substrates, limiting their potential applications. Flexible versions do exist, although they require special production techniques and/or materials. Now, however, scientists from Stanford University have created thin, flexible solar cells that are made from standard materials – and they can applied to just about any surface, like a sticker.
